Popeşti-Leordeni is a town in Ilfov County, Romania, 9 km south of Bucharest, although from the northern edge of the town to the southern edge of Bucharest the distance is less than 100 m. The town's population is 15,115 inhabitants. Most of its inhabitants commute to Bucharest, with Popeşti-Leordeni being seen as a satellite town of the Romanian capital.

Popeşti-Leordeni was historically the site of two separate villages — Popeşti (name derived from popă, "priest" - akin to the word "pope") and Leordeni (name derived from leurdă, "ramsons" or Allium ursinum).

The villages were first attested during the 16th century: Leordeni was a domain of the Băleanu family of Wallachian boyars, while Popeşti was included in the lands belonging to ancestors of the chronicler Radu Popescu. The latter was inherited by the Phanariote nobleman known under the name Alexandru Conduratu, who settled it with Bulgarians from around Nikopol and from the Banat; the newly-created locality was named Popeşti-Conduratu or Pavlicheni, in reference to "Paulicians" (a tradition designated the Roman Catholic group of the Bulgarian community by the names of their ancestors).

Popeşti and Leordeni were united into a single commune in 1873; boyar lands were divided by successive land reforms, and the Conduratu manor house was passed to the Costa-Foru family (whose member Constantin Costa-Foru was a well-known journalist in the interwar period).
